Functionality

vioplot (0.3) is backwards-compatible with vioplot (0.2). The following features are supported:

vioplot() generates a violin plot by plotting a violin for each group of variables.

vioplot() also takes additional arguments to specify main, sub, xlab, and ylab as used in plot or title. Graphical parameters can be passed to plotting parameters.

vioplot() can take vectorised forms of colour variables col, border, and rectCol to modify the colours separately for each violin respectively. This also applies to a new variable lineCol to modify the colour of the boxplots.

vioplot.formula() is enabled to take formula and dataframe inputs as used for boxplot and stats operations. The default axes labels are the variable names used for the formula and names are factor levels.

additional areaEqual, plotCentre and side options enables further customisation.

See the NEWS.md file for more detail on added features in the 0.3 release.
